There was '50s nostalgia in the '80s, though: Happy Days and Back To The Future.

There was some interesting counterculture in the '40s and '50s, but how could there not be when the dominant culture was so conformist and bland. You have to dig at least a little for that stuff today, because those countercultures didn't really become legible until the '60s, when they were already changing into something less interesting.
